l have horrible smelly ants that are covering my climbing and rambler roses and a few other shrubs to a height of 12 feet up.
They are not farming aphids - there are none: they assemble in their hundreds at the junctions of branches on the roses or wherever the bark is damaged. At the least disturbance they drop all over anyone passing, squirting their smelly formic acid in such quantities that, when attacked like this, you have to change all your clothes and wash your hair to get rid of the smell.
l have tried squirting them with a vinegar and garlic mixture, l have dusted them and round the rose roots with ant powder, with no effect, and l have tried putting ant bait out but they don't touch it.
The green woodpeckers don't eat them either.
Does anyone know how to get rid of them please? There are bits of garden where l now hate working because of them.
